Murabba'i yana ɗaya daga cikin siffofi na asali da aka sani tun zamanin da. Wannan siffar ba wai kawai tana da ban sha'awa ba ne daga mahangar lissafi, har ma tana da amfani mai yawa a fannoni daban-daban, tun daga gine-gine zuwa ƙira da fasaha. Wannan labarin zai bincika murabba'in sosai, yana bincika halayensa na musamman, da kuma tattauna aikace-aikacensa da mahimmancinsa a rayuwar yau da kullun.
Ma'anar Murabba'i
Murabba'i murabba'i ne mai kusurwa huɗu mai gefuna huɗu masu tsayi daidai da kusurwoyi huɗu masu ma'auni iri ɗaya, wato digiri 90 (kusurwoyin dama). A wata ma'anar, murabba'i nau'i ne na musamman na murabba'i inda gefuna da kusurwoyin suke iri ɗaya. A cikin bayanin geometric, idan muka kira murabba'i mai kusurwa A, B, C, da D to tsayin AB = BC = CD = DA kuma kusurwoyin ∠A = ∠B = ∠C = ∠D = digiri 90.
